Abstract

A field experiment was conducted with 'Chowghat Orange Dwarf' ('COD') x 'West Coast Tall' (WCT') and 'West Coast Tall' coconut (Cocos nucifera L.) cultivars under laterite soil condition, to study the influence of drip irriga- tion on nut yield and nut characters during 1993-1 999 at Kasaragod, Kerala. The treatments consisted of 3 lev- els of drip irrigation [33, 66 and 100% of open pan evaporation (E,) daily] along with basin irrigation (100% of E,) and rainfed control. Drip irrigation at 66% of E, (27 litres waterlpalmlday during December-January and 32 litres of water1 palm per day during February-May) resulted in water saving and the nut yield was on a per with 100% throught drip and 100 % of E, through basin irrigation. Rainfed control and 33% of E, through drip treat- ments recorded significantly lower nut yield in both the cultivars. The nut characters like nut weight, copra thick- ness, and copra content were superior under irrigated treatments compared to rainfed control.
